5) A substance requires 345 J of heat to raise the temperature from 17 oC to 48 oC. . If the mass of the substance is 25 g, what is the specific heat of the substance?
6)
18 g of zinc was heated from 50°C to 85°C. How much energy was used to heat Zn? (Specific heat capacity of Zn 0.440 J/g °C)

Match the mixture with the substance// i really need on this guys (it’s a pic btw)

Hey can you me with this i really need y’all

The table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 9 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of tthe table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 9 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.
